Description

Technical Field

[0001] This utility model relates to the field of rubber roller production technology, specifically to a clamping and fixing device used in rubber roller production. Background Technology

[0002] During the production of rubber rollers, the rubber is usually first fixed to the outside of the metal roller core by blow molding or bonding, then vulcanized, and then the surface of the rubber is surface-processed by a lathe to ensure the surface quality of the rubber roller.

[0003] When performing surface treatment on rubber rollers, the process is generally carried out on a lathe. First, one end of the rubber roller is clamped in a three-jaw chuck, and then the other end of the rubber roller is positioned and fixed by a top cone. Although this method of fixing rubber rollers is relatively common and simple to operate, when processing longer rubber rollers, this fixing method can easily cause the rubber roller to develop a slight curvature in the middle under its own weight, which will affect the accuracy of the processing. Furthermore, since the other end of the roller is only supported by a top cone, the surface in contact with the top cone can easily undergo slight displacement when the roller rotates, causing the axis to shift, which will affect the processing accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that in existing rubber roller surface treatment methods, a three-jaw chuck is commonly used to clamp one end and a top cone is used to position the other end. However, when processing long rubber rollers, the weight of the roller itself easily causes a curvature in the middle, and the top cone is prone to displacement and axis misalignment, affecting processing accuracy.

[0005] To solve the above problems, the technical solution adopted by this utility model is a clamping and fixing device for rubber roller production, including a machine tool body. One end of the machine tool body is provided with a three-jaw chuck structure, and the other end of the machine tool body is provided with a top cone structure. A roller body is provided between the top cone structure and the three-jaw chuck structure. An auxiliary support structure is provided below the machine tool body. The top cone structure includes a cone that is set on one end of the roller body. A cover is fixed on the outside of the cone. Several threaded holes are obliquely opened on the side of the cover. A threaded push rod is rotatably connected to the threaded holes. A rubber head is fixed at one end of the threaded push rod. The auxiliary support structure includes a pair of limiting rods fixed above the machine tool body. Several support plates are slidably provided on the outside of the limiting rods. An extension rod is fixed at the top of the support plate. A limiting hole is opened on the upper side of one end of the extension rod. A top plate is slidably provided on the limiting hole. A connecting rod is fixed on the upper side of the top plate. An arc frame is fixed at the top of the connecting rod. A pair of rollers are rotatably provided on the top of the arc frame. A compression spring is clamped between the top plate and the bottom end of the limiting hole.

[0006] As a further embodiment of this invention, the rubber head is placed against the outer surface of one end of the roller body, which can play a fixing role.

[0007] As a further embodiment of this utility model: a screw hole is provided on one side of the support plate, and a tightening bolt is rotatably connected to the screw hole. One end of the tightening bolt abuts against the side of the limiting rod, which can fix the position of the support plate.

[0008] As a further embodiment of this invention: the extension rod is made of carbon fiber, which is elastic and allows the roller to always be pressed against the surface of the roller body, thus providing a supporting effect.

[0009] As a further embodiment of this invention: the side of the roller abuts against the surface of the roller body, which facilitates defining the position of one end of the roller body.

[0010] Compared with the prior art, the advantages of this utility model are as follows: This application adds a threaded push rod, one end of which is inclined and abuts against the surface of the roller body. This not only fixes one end of the roller body, but also makes the contact between the cone and the end face of the roller body more stable. An auxiliary support structure is added, with several extension rods set below the roller body. Rollers are used to contact the roller surface for support, which can alleviate the deformation of long rollers caused by their own weight, thereby improving the processing accuracy.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0021] Combined with appendix Figure 1 , 2 4. It can be seen that the machine tool body 1 is provided. One end of the machine tool body 1 is provided with a three-jaw chuck structure 2 for clamping one end of the roller body 3. The other end of the machine tool body 1 is provided with a top cone structure for positioning the other end of the roller body 3. The roller body 3 is provided between the top cone structure and the three-jaw chuck structure 2. An auxiliary support structure is provided below the machine tool body 1. The top cone structure includes a cone 4 that is topped on one end of the roller body 3. A cover 5 is fixed on the outside of the cone 4. Several threaded holes 5.1 are obliquely opened on the side of the cover 5. A threaded push rod 6 is threadedly rotatably connected in the threaded holes 5.1. Rotating the threaded push rod 6 can make it move in the threaded holes 5.1. A rubber head 7 is fixed on one end of the threaded push rod 6. The rubber head 7 abuts against the outer surface of one end of the roller body 3 and can play a fixing role.

[0022] Combined with appendix Figure 1 , 35. It can be seen that the auxiliary support structure includes a pair of limiting rods 8 fixed above the machine tool body 1. Several support plates 9 are slidably arranged on the outer side of the limiting rods 8. A screw hole is opened on one side of the support plate 9, and a tightening bolt 16 is rotatably connected to the screw hole. One end of the tightening bolt 16 abuts against the side of the limiting rod 8, which can fix the position of the support plate 9. An extension rod 10 is fixed at the top of the support plate 9. The extension rod 10 is made of carbon fiber and has elasticity, which can keep the roller 14 always pressed against the surface of the roller body 3, and at the same time provide support. A limiting hole 10.1 is provided on the upper side of one end of the extension rod 10. A top plate 11 is slidably provided in the limiting hole 10.1. A connecting rod 12 is fixed on the upper side of the top plate 11. An arc frame 13 is fixed at the top of the connecting rod 12. A pair of rollers 14 are rotatably provided at the top of the arc frame 13. The side of the rollers 14 abuts against the surface of the roller body 3, which facilitates limiting the position of one end of the roller body 3. A compression spring 15 is sandwiched between the top plate 11 and the bottom end of the limiting hole 10.1, which can push the top plate 11 to move upward, so that the rollers 14 are always pressed against the surface of the roller body 3.

[0023] The working principle of this application is as follows: When processing the roller body 3, the roller body 3 is first suspended above multiple auxiliary support structures so that the roller 14 can contact the roller body 3 and the support plate 9 can slide. The position is adjusted according to the different lengths of the roller body 3 to facilitate uniform support. After adjusting the position of the support plate 9, the top bolt 16 is rotated to fix its position. This structure can assist in supporting the roller body 3 from below and prevent it from undergoing slight deformation due to its own weight.

[0024] Then, clamp one end of the roller body 3 in the three-jaw chuck structure 2, then move the top cone structure so that the cone 4 is positioned at the center of the other end of the roller body 3, then rotate the three threaded top rods 6 so that the rubber head 7 can abut against the outside of the other end of the roller body 3, thus fixing the other end of the roller body 3, and then processing can be carried out.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
